COLLAPSIBLE UMBRELLA.

Application led- April 3, 1926, Serial No.. 99,514, and in Germany July 2, 1925.

The present invention relates to an umbrella with telescopical sliding members. The novelty consists in this that a stick member which serves as the handle and is slidable between the struts and the ribs supportedat both its ends when the stick is extended, b inner-lying stick parts, at the lower end by a firm connection with the lowest inner stick member, and at its upper end by a piston-like guide capable ot' sliding in the handle tube.

Moreover, according to the invention ythe lumbrella stick is of such a kind that a middle member slides into the upper stick mem ber and these and the slide to which the struts are attached arel capable of .sliding together into the handle tube with the piston guide so that the handle tube lies be tween the struts and the ribs.

A constructional form of the umbrella is lshown by way of example in the accompanying drawing, in which Figure 1 is a longitudinal section through the umbrella, only a single rib on one side being shown,

Figure 2 a longitudinal section through the inner parts of the stick to an enlarged scale,

Figure 3 a longitudinal section through the umbrella frame also to an enlarged scale with the parts slid together, some ot the parts being in elevation,

Fi ure 4 shows the portion of a rib, to whic the strut is pivoted, in longitudinal section,

Figure 5 the same part in plan view,

Figure 6 a diagrammatic cross-sectional view of the rib, to an enlarged scale, and

. Figure 7 also toanenlarged scale, a longitudinal section through the ends ot the two parts of a rib, where they meet.

1, 2, 3 and 4 are the parts of the stick,

which are capable of sliding telescopically one in the other. The lower parts are embraced by a part 5 forming the umbrella handle, into which theupper arts 3 and 4 of the stick are capable of sli ing with the aid of a guiding plunger (S lixed tothe part 3. 7 is a spring within the part 3 of the stick, the wall of which is at this place reinforced vby an inner short piece of tube 8. 'lhe spring serves the purpose both of locking the part 4 of the stick when extended and also of securing the sliding part 9, when the umbrella is open. The spring is released by hand when the umbrella is to be closed, and, when the parts of the stick are slid together, by being pushed aside by the upper end of the part 1. Owing to the tact, that the outer tube 5 is guided on the third inner part 3 of the stick from the bottom, the lower parts of the stick, 1, 2, 3 and 5 are secured by a single spring 1l which is tixed to the guiding member 6 and engages over the upper edge of the part 5 of the stick. The spring 1l must be released by hand. l2 .is the crown of the umbrella. 13 and. 14 are the two parts of the rib, which are capable of being slid together. 17 is a strut one end of which is pivoted to the sliding part 9 and the other to the rib. On the parts of the stick beingl slid together the lower part 5 of the stick, as shown in Figure 3,-is slid between the struts and the ribs into the upper half of the umbrella frame or even close up to the upper pivotal joint of the strut 17, so that the ribs and struts are prevented from resting one against the other,

15 is a guiding sleeve fixed to the part 14 of the rib and 16 a guiding sleeve which is fixed to the part 13 of the rib, but is capable of. sliding on the upper part 14 of the rib. The strut 17 is not carried up as is usually the case, as far as the outer part 13 of the rib, but is pivoted to a member 18 on a sleeve 19 which is capable of being slid on the rib right up to the crown 12 of which, on the umbrella frame being extended, is secured by a projection 2l on the extension 20 of the part 18, which reaches between the parts of the rib to the outer end of the part 14 becoming wedged between the sleeves 15 and 16 on the rib. Y

Notches or similar depressions are rovided on the ribs, by which the parts o the rib can engage with one another, when the latter is extended. Thus for instance the art 13 of the rib is provided with a shouler 22, with which the said part of the rib rests against the sleeve 15, as long as it is not stretched out straight. For keeping the Isleeve 15 pressed against the shoulder 22 a sprin 23 is provided on the part 13 of the rib w 'ch spring embraces, the sleeve l5. On the part 5 of the stick being slid over the strut 17 when the umbrella is pushed together (Fig. 3), the part 14 of the rib is drawn close against the umbrella stick, while the unsupported end of the rib provided with the ball point 24 is forced outwards over a thickened part 25 on the umbrella handle. Through the rib being forced out in t is manner, the sleeve 15 is caused tov leave the shoulder 22 thus enabling the parts 'of the rib to be pushed in at the same time as the part 5 of the stick.

2,6 is the umbrella cover which is fixed to the iding sleeve 16 as well as to the ends of t e ribs and confirms the fold 27, on cthe umbrella being pushed together. 28 is a loop for instance of leather provided on the end of the stick. This loop is used as a handle umbrella is pushed together between the struts and the ribs, and a guiding member fixed on a. section with the stick and capable f of sliding within the hollow handle and of acting' as a su ort at the u er end of the hollow handleplor the sectifiiips of the stick within the hollow handle when the stick is extended, the lowest section of the stick'bein secured inside the handle to the bottom en of the said handle as set forth.

2. A. collapsible umbrella comprising in combination a stick, a lurality of ribs, both the stick and the ribs eing in sections and capable of being slid together telescopically, a plurality of struts for su porting the ribs on the stick when the umbrella is o en, a slide to which the struts arc attache and a hollow handle which extends when the umbrella is pushed together between the struts and the ribs, and a guiding member fixed on a section with the stick and capable of slidingwithin the hollow handle and of acting as a support at the upper end of the hollow handle for the sections ofthe stick within the hollow handle when the stick is extended, the lowest section of the stick being secured inside the handle to the bottom end of the said handle, and the topmost sec,- tion of the stick being capable of sliding over the section next below it and of slidin f with it and the guiding piston and the saiil sliding tube to the struts into the hollow handle, as set forth.

3. A collapsible umbrella comprisin in combination a stick, a plurality of ribs, oth the stick and ribs being in sections land capable of being slid together telescopically, a plurality of struts for supporting the ribs on the stick when the umbrella is open, a slidable member to which the up er end of the strut is pivotally attached amil which is capable of sliding on the upper part of the upper section of the rib, guiding rings on the upper and lower'sections of the rib for guiding them with res ect to each other, an extension on the said shdable member, a rojection on the said extension capable o becoming wedged between the two guiding rings on the rib sections by the rib being extended, and a hollow handle which extends, when the umbrella is pushed to ether, between the struts and the ribs into tie upper half of the collapsed umbrella, as set forth. v

In` testimony whereof I have signed my name to this specication.
